The eclipse has come with much fanfare and now it’s over. We’ve invested so much eager anticipation, hard work and excitement into seeing this one that now we’re left wondering what to do next. Here are some ideas:
Process and upload your images. They can go on our Forum, on our Facebook page, in our 2018 calendar and to our Communications Officer, Paul, for use on our website in the future. Also, Dawn is collecting images for a slide show for our September general meeting.
Donate your undamaged solar glasses. At the September meeting, we’ll have a large box to collect used solar glasses. We’ll send them to our friends at Astronomers Without Borders who will donate them to schools and clubs in South American for the 2019 eclipse going over Chile and Argentina.
by RCA Member Teela Bright The day started out early as I woke up around 3:00 am, thinking of my incredible luck in having my name drawn by RCA for such a spectacular event — reviewing in my mind the smiles and amazing support I have had from RCA, knowing in my heart that they would all be with me during this flight, and then some — and knowing I have been blessed with perhaps a once-in-a-lifetime chance to see something so amazing and beautiful.
RCA is working together with our friends at Portland Audubon to raise awareness about light pollution. On September 15 turn off your non-essential lights from dusk to dawn, and then to go outside and check out the night sky! Iconic buildings all around Portland will be going lights out to raise awareness about light pollution, including the Fox Tower, the Wells Fargo Tower, OMSI, Bonneville Power Administration, 200 Market, the 911 Federal Building, Montgomery Park, Holladay Park, City of Portland buildings, and 1201 Lloyd! The Lloyd EcoDistrict is cosponsoring the launch event with their own district effort: LightsOut Lloyd PDX.
RCA Volunteers shared their time, telescopes and knowledge with over 1,000 people at the OMSI viewing party for the total eclipse in Salem, OR on August 21. Volunteers showed up Saturday afternoon to help set up and many slept overnight in the gravel lot of the Oregon State Fair Grounds to be ready for Monday’s early morning. With 14 wonderful volunteers, there were many activities to engage the attendees of the event. There were 7 telescopes set up for public viewing of the sun and Venus. There was also an eclipse diagram provided by Robin Baker, an RCA astro-photography display and an Oregon roadmap showing path of totality by Paul Salvatore. Lastly, there were activities for kids of all ages that included UV bead bracelets, moon phase wheels, and solar eclipse word searches.
Many thanks to Robin Baker, Paula Frenchen, Yara Green, Bob Hansen (from sister club in Vancouver, BC), Robert Nelson and family, Mario and Maria Pedraza, Marc Singleton, April South, Mike Sutherland, and Do and Uyen Tran for their enthusiasm and generosity on such a spectacular occasion.
It was billed as the “great American” eclipse, but I’d rather call it the “great global eclipse.” One of my pleasures on Eclipse Day was meeting Graham and Margaret Duhig, members of BDAA, the British Deaf Astronomical Association. I spent the night before the eclipse at a small hotel downtown so I would wake up in the morning close to the train station. When I checked in, I noticed a senior couple signing to each other. The next day as I checked out at 5:15 a.m., the hotel clerk told me I had just missed sharing a taxi with the English astronomers who were here to see the eclipse. When I got to the train station, they were there, so I introduced myself and gave them a card from RCA. They showed me a picture of their group and gave me their contact information. We shared a train ride down and they set up near the capitol steps for the event. There’s more to the story, but I’ll end it by saying I encourage you to visit their website and friend or like them on Facebook.
I had the pleasure of welcoming the Hardel family (Suzelle, Stephane and their teen daughters, Dilys and Maelle) of Normandy, France to Oregon for the Total Solar Eclipse (TSE). Having little interest in astronomy at the time, they were visiting Spain during the 1999 eclipse that went through France. Like so many members of our club, Suzelle, a member of two Norman astronomy clubs, was lured into astronomy in 2007 when her long-time photography hobby blossomed into astrophotography. By March, when Suzelle was finally granted leave for an extended holiday to the USA, all accommodations along the Path of Totality from Oregon to Idaho were booked. So, she reached out to fellow astronomy clubs in both states asking for advice on accommodation. Having been unexpectedly shut out from OSP, I found myself in the same situation, i.e., all dressed up and nowhere to go. So I immediately extended her an invite to my little house in Portland, while warning her that there could be clouds west of the Cascades.
Trout Lake Star Party is an annual event that is especially welcome and wonderful, but this year there were a couple of reminders that ultimately, moving cars and expensive telescopes don’t mix well and we need to be careful. Throw in a couple extra accident factors, like people walking around in the dark and cars flashing white light across the field destroying everyone’s night vision and it becomes clear that we need to be cautious as we take our cars out at night.
By 1920, Milankovtich completed the book he began writing during the World War: Mathematical Theory of Heat Phenomena Produced by Solar Radiation. In this work, Milankovtich set out the mathematical tools he developed by which he calculated and described the amount of solar radiation received planet wide on Mars, Earth and Venus. As mentioned in the introduction to this series of articles, his calculations for Mars and Earth proved accurate. But, because he was unaware of Venus’ dense atmosphere his calculations of Venus’ were not even close — spacecraft probes have measured surface temperatures over 850 degrees Fahrenheit and pressures equal to the pressure 3000 feet underwater. The book received more attention from the public for his Mars’ results than it did from geologists interested in Earth’s Ice Ages because in the first decades of the 20th Century, the popular press was filled with stories about Martians and canals on Mars.
We've already started on the 2018 calendar, and we're looking for your help. As is traditional, we are looking for your great astrophotos, so, please keep an eye out for the URL to where you can submit them, which should be available shortly. Also, as this next year is the 30th anniversary of the club, we would also like your help in providing any historical images you might have. If you have photos from the past 30 years of group gatherings, special events, star parties, or even just pictures of club members showing off the stylish fashions of the day, we would be interested to see and possibly use them in the calendar and other publications over the course of next year. For more information contact our Calendar Manager, David Novotny.
